I am attempting to hook up a 12-volt water pump to an 110 outlet.
I bought an AC/DC switching adapter to make the conversion. Intended on wiring a black and red wire to a black and red wire. But my power brick also has a blue and white wire. I'm assuming these are some sort of feedback wires for the protection of PSU's but I don't know what to do with them.
When I ignore them and just hook up the red and black wires the power supply decides to stop sending power through, it shoots small test bursts of electricity through and never powers the pump. is there an easy way to override the protection mechanism if that is what is happening? If that is not the issue what are the white and blue wires?
Power brick specs:
Input: 100-240VAC, 50/60Hz, 4.0A
Output: 12v 15A, 180w MAX
